In a recent groundbreaking study conducted by researchers at the School of Life Course & Population Sciences in collaboration with ZOE, a stark revelation has emerged: only half of the population is matching the nutritional value of their meals and snacks. This dietary disparity is exacting a severe toll on health indicators such as blood sugar and fat levels. The good news is that addressing this issue may be surprisingly straightforward: by simply adjusting your diet.
The study, featured in the European Journal of Nutrition, delved into the snacking habits of 854 participants from the ZOE PREDICT project. Dr. Sarah Berry, hailing from King’s College London and serving as the chief scientist at ZOE, emphasised the widespread prevalence of snacking, with a staggering 95 percent of the population partaking in this habit. Astonishingly, nearly a quarter of our daily caloric intake is derived from snacks. Dr. Berry underlines the potential remedy: "Swapping unhealthy snacks such as cookies, crisps, and cakes for healthy alternatives like fruit and nuts is a remarkably simple way to enhance your health."
Contrary to common misconceptions, the analysis underscored that snacking itself isn't detrimental; rather, it's the quality of snacks that truly matters. People who opt for high-quality snacks, such as nuts and fresh fruits, are more likely to maintain a healthy weight and experience improved metabolic health and reduced appetite compared to those who either abstain from snacking or indulge in unhealthy options.

Alarming findings also revealed that a quarter of individuals admitted to consuming unhealthy snacks alongside their regular meals. These poor-quality snacks, often heavily processed and laden with sugar, triggered heightened feelings of hunger and were closely associated with worsened health markers.
The repercussions of indulging in unhealthy snacks extended beyond the taste buds. These snacks were linked to elevated body mass index (BMI), increased visceral fat mass, and higher post-meal triglyceride levels—all risk factors for metabolic disorders like obesity, stroke, and cardiovascular disease. Timing also played a crucial role; late-night snacking, specifically after 9 p.m., was associated with worse blood indicators. These late-night snacks typically consisted of calorie-dense, high-fat, and sugary items.
Dr. Kate Bermingham, a senior scientist at ZOE and also affiliated with King’s College London, emphasised the paramount importance of food quality in achieving positive health outcomes. She stressed the importance of consuming a balanced diet, rich in fruits, vegetables, protein, and legumes, as the optimal path to enhance one's health.
